Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm .~>Uh3S  
Type: Double Bounces e(t,~(  
The '****' denotes a possible internal focus b d!|/Lk  
RMS is the RMS spot radius on axis at the primary wavelength.  B6| g2Tt  
RMS values of 0.00 indicate that an accurate RMS {
Ftz4y)6  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is 4^|;a0Qy]  
non-rotationally symmetric or uses non-standard surfaces.
